Help w/ Fast Blinker

[stewartsj3]

New here, so be gentle on me.

Have an '07 Tahoe LTZ and a few weeks ago the passenger-side blinker started blinking fast. Naturally I checked the bulbs and saw that the rear blinker bulb was out so I replaced it. I also replaced the rear driver-side bulb for safe measure. However, the fast blinking continues.

I checked all other bulbs and one of the rear taillight marker lights was out so I replaced those as well. Then one of the DRL bulbs was out so replaced those.

Fast blinking continues.

I've checked fuses, at least the ones that indicated anything to do with brake lights or signals and they all appear to be fine.

Any other ideas as to what it might be? Possibly the relay? If it's the relay, where is that located? Any help is appreciated.

Flasher/relay, google the location or wait for someone here that knows. I don't

Don't know if this helps...

This has happened to me on two different vehicles...

One- had an '02 Chevy. After pulling a trailer, would leave the pigtail harness connected. I eventually found that that would cause the increased speed on the signal and sometimes short. It was weird because it would not do it when tied into the trailers.


Two- continued to happen to me on an '03 Ram. Right signal began to blink fast and within a few days, my right taillight blinker would completely short out. After replacing about 10 bulbs, I decided to replace the entire tailight assembly because I could not fix the short... That fixed the problem.
